We've all been there: You're sitting at home, watching The Matrix, and the dialogue is so quiet that you turn up the volume to hear it, when BAM! An action scene comes in, shakes your floor and wakes up all your neighbors. Sound Lock is a simple app for Windows that will save you from these embarrassing moments.

Sound Lock sits in your system tray and lets you set the maximum volume for your entire computer, so no matter how loud things may get, you won't wake up your neighbors. Just install it, click on the system tray icon, and move the slider down until you reach your desired level. When you watch your movie, the really loud parts should be lowered to the same level as the quiet parts. We know, we know, the volume differences are in there for a reason—but when it's late at night and you don't want to be the jerk that shakes the walls, this is a great solution.
